无线(手持)吸尘器经常会发生自动关机,但偶尔有线吸尘器也会遇到这种情况。我们将探讨可能的原因并提供一些修复建议。准备好为你的戴森吸尘器进行一些简单的维护吧。

第一步

它是什么表现?

  • 按下扳机时,它是表现为快速开启和关闭的“脉冲”式运行吗?这是无线吸尘器的一项设计功能,目的是为了防止吸尘器在试图清理堵塞时损坏自身。通常吸尘器会脉冲运行几个周期,然后彻底关机。你需要等待片刻,它才能重新启动。
  • 它是运行一段时间后自动关机吗?这种情况在戴森有线吸尘器上更为常见,但无线型号也可能发生。同样,这也是为了防止吸尘器电机过热而设计的保护功能。
  • 在这两种情况下,问题通常都是吸尘器过热(触发了电机内的热保护功能),或者是由于缺乏气流导致电机运行异常,从而触发了吸尘器的控制电路(无线型号)。主要有两个原因:堵塞和滤网过脏。我们将首先排查堵塞,但在此之前,我们需要先检查无线型号的电池和充电问题。

电池电量低

虽然这仅适用于无线型号,但在进行其他故障排除步骤之前,请务必先将电池充满电。

  • 电池电量低会导致设备自动关机,以防止电机或电池损坏。
  • 如果电池无法正常充电,你应该更换电池。
  • 检查在充电或更换电池后,设备是否仍然会自动关机。

充电故障

部分戴森无线吸尘器可能会出现运行约 10 秒后自动关机的情况(没有脉冲)。一种可能的修复方法:

  • 将充电器从电源插座上拔下。
  • 重新将充电器连接到电源。
  • 将吸尘器放回充电座上,并按住扳机 15-20 秒。按下扳机时设备不会有反应。
  • 将吸尘器从充电座上取下,它应该就能恢复正常了。

吸尘器堵塞

我们这里主要针对无线吸尘器,因为它们最常出现这种关机问题。对于有线吸尘器,你应该 查看此页面关于堵塞的内容

戴森无线吸尘器有几个常见的堵塞位置。只需遵循“气流路径”去检查即可。

  • 首先检查清洁头。戴森无线吸尘器的清洁头拆卸清理非常简单。
  • 由于它们配有一体式滚刷,从末端取下后,即可轻松进入滚刷后的风道。
    • 通常需要先拆除一些护罩,如果你无法看到风道内部,请做好进行拆卸的准备。
    • 气道中有一个部件可以拆下,以便更好地清理堵塞,只需一枚硬币即可打开。
    • 如果发现堵塞,清除它,重新组装设备并测试。如果还是不行,请继续后续检查。
  • 接下来检查吸尘杆,看里面是否有堵塞。由于它是一根直管,堵塞的可能性很小。
  • 下一步是从机身拆下吸尘杆,观察空气进入集尘盒的开口。那里有一个导流片,有时会卡住杂物。
  • 为了更好地进行后续步骤,你需要拆下集尘盒。
    • 除了打开集尘盒的锁扣外,还有一个必须松开的锁扣。
    • 拆卸集尘盒可能有点麻烦,稍微旋转一下可能会有帮助。
  • 检查气旋主体的中心内部是否有杂物。此时清理一下滤网也是个好主意。
  • 重新组装并测试,如果还是不行,进入下一项。

滤网过脏

戴森吸尘器非常依赖滤网来捕获初次通过的大颗粒杂质和随后的微小颗粒。下一步是检查所有滤网。

  • 我们已经检查并清理了气旋内的滤网(这是导致吸力损失的主要原因)。
  • 在无线型号中,气旋中心位置还有一个滤网,它经常会变脏,必须进行清洗或更换。
    • 当滤网过脏时,可能会导致无线设备出现脉冲式运行。在某些情况下,情况可能会更简单。
    • 可以通过流水冲洗滤网,但在清洗前先将滤网拆开会更有帮助。
      • 滤网内部有一个塑料中框,既能帮助其保持形状,也使得清洁难度增加。
      • 要拆下它,你需要小心地松开滤网顶部的三个卡扣。
      • 拆下后,滤网可以更有效地挤压和轻柔拧干。
      • 请记住,戴森建议任何时候清洗滤网后,都应晾干至少 24 小时后再装回。
  • 通常还有一个电机后置滤网(通常是 HEPA 滤网),也应检查是否过脏。在无线型号上,这通常兼作电机上方的端盖。
  • 戴森生产的机型繁多,无法针对每款机型提供滤网位置的详细信息。
  • 通常情况下,吸尘器在电机前方总会有预滤网,需要定期维护,Cinetic 系列机型除外(它们没有该滤网)。
  • 所有戴森吸尘器在电机后方都有一个滤网。在某些情况下(如 Cinetic 系列),必须通过拆卸才能触及,且该滤网被视为终身滤网。
  • 如果你已经清理或更换了所有滤网,检查吸尘器是否运行正常。如果正常,大功告成;如果不正常,进入下一步。

开关故障

此时,特别是对于无线型号,检查开关是一个好主意。

  • 无线型号使用微动开关作为扳机开关,如果它发生故障或接触不良,吸尘器会意外关机。
  • 微动开关构成的电路会被控制板感知。随后控制板会为吸尘器供电,使其运行。
  • 你可以通过断开电池连接,并将开关的一根导线从设备上拆下,然后使用导通测试仪来测试开关。由于开关通常预先连接到电池保护板上,这可能比较困难。
  • 如果可能,请直接在设备上测试开关,而不是将其拆下。某些故障(尤其是间歇性故障)最好通过在设备运行位置晃动部件来发现。
  • 你可以尝试用物体固定住开关,使其保持在开启位置。
    • 观察吸尘器在不动的情况下是否会关机。
    • 如果关机了,问题不太可能是开关,更可能是电机或控制板的某种热问题。
    • 如果没有关机,重新给它充电,并尝试在改变对开关施力方式的同时测试设备;如果发生间歇性关机,你就找到了问题所在。
  • 如果开关测试正常,进入下一步。

控制板或电机故障

此时,原因可能比较严重。控制板不是一个容易获得的零件,更换过程也相对复杂。在许多情况下,它和电机是一起购买的,因为它们通常作为一个单元出售。如果所有其他问题都已排查过,你可以将它们一起更换。

After eliminating all possible causes with a pulsating V6 Absolute Dyson's "Experts" told me that the main body needed replacing, they gave me the required part number 967911-03. Dyson no longer stock this part so I bought a genuine Dyson part from Ebay. After fitting, this new part cured the pulsating but would not drive the motorised lower brush. The new part was installed on a fully working V6 Absolute and it still did not power the motorised lower brush. I presume the new part 967911-03 was faulty and returned it to Ebay and received a full refund. After contacting Dyson's "Experts" again I ordered another new genuine Dyson part 967911-03 from a different supplier. This part had the same problem, no pulsating but not driving the bottom brush. To be clear, the faulty V6 has been cleaned throughout including dismantling and cleaning the Cyclone, there are no blockages. Does anyone have an answer to this problem? Could the new parts be faulty and how can they be tested?

Check the electrical contacts from the main motor body (which you replaced) and the clear bin. Those contacts connect to conductors that run along the upper edge of the bin and lead to the contacts where the wand is attached. If there are problems with any of those contacts the brush head won't spin. I suspect the problem to be the contacts on your new motor because you even swapped the motor onto a functional V6 and then the V6 brush didn't work.

Here's a link to an answer that might have helpful info.

Hello Bill,

Thanks for your suggestions. The problem is that this is the second new motor I’ve tried, both results with no spinning brush on both V6s. I would be very surprised if both new motors required the contracts to be cleaned.

I’m reluctant to start cleaning the contacts on the new motor because it would mean I wouldn’t be able to return it.

The contacts on the bin are okay and I have continuity to the wand terminals. I’ve tried swapping the bin from the working V6 and the result is the same. The only thing left is to buy a new bin, however I don’t think that would cure it because the new motor produces no brush spin on a working V6. I hope I’m making sense here.

You're making perfect sense. That's bizarre that both motors would give a no spin condition, You did the next thing I would have tried which is checking continuity to the brush motor. I understand about your reluctance to clean contacts. Are you able to check the motor power outputs to see if you are actually getting voltage at the terminals that would go to the bin and then to the wand connector? I have heard of defective motor boards that people have had to modify because of no brushroll output. Getting two of them seems unlikely. Since you are buying them on eBay, though, there is a small possibility that the units were parted out with the idea that the brush head was bad. Since the motor still ran it was assumed to be fine. So a voltage check is in order. If I recall correctly it should be around 18-21 volts or so. If you can't get voltage at those contacts, then you need to check the motor board for defects. You should also check the working V6 for voltage at it's output contacts.
